The4 present invention has reference to hoists placed on the outside of a building, and it relates more especiallyv to a bucket elevator for handling concrete, plaster and 6 the like.

Primarily the object of this invention is to produce an im roved ap aratus of the class aforesaid, particularlyla apted for buildings of medium height and capable of raising 10 from thev ground, a bucket load of material and to deliver the "same automatically through a window opening at a desired level.

A secondary object is to provide an apparatus of the nature mentioned wherein a carrier for the material containing bucket is guided .along a-solitary mast or upright, and arranged to leave free access to the .bucket from two sides thereof.

Another object is the provision in an apparatus of the type set forth of sin le braces reaching out from one side of a win ow open? ing at each iioor. level, for holding the upright guide -in vertically aligned position.

A further object is the production of an apparatus of the character disclosed having cooperating tripping devices respectively connected upwith the bucket carrier and the.v

mast holding braces, the arrangement being such as to cause the device on the carrier to tip the bucket for discharging its contents thru selective window openings. u

.A special object is to supply an apparatus of the kind referred to, which shall be revversible in order that the mast, rbraces, and

the bucket with its tipping device -may be placed along either side of a vertical row of window openings and the hoisting cable conveniently led in one direction or another away from the mast. A

40 A general object is to furnish an apparatus for the purposestated, which shall be composed of few, simple and light, but strong parts; quickly erected or taken down; convenient and eiiicient to operate; durable and l5 easily maintained in working order, andca-V pable besides, of beingeconomically manufactured.

u vOther objects and advantages of the invention will become apparent as the specifica- 0 tion proceeds.

With the aforesaid objects inI view, the invention consists of the novel combinations and arrangements of parts hereinafter described in their preferred. embodiments, pointed out in the subjoined claims and illustrated on thel annexed drawings, wherein like parts are designated by the same reference characters throughout the several views.

enerally described, the invention under consideration, includes in its organization,

a single upright that is disposed in parallel spaced relation with respect to one side of the window openings thru a building, wall. Braces which engage the sides of the walls adjacent the windows, reach therefrom to the of this improved mast and serve to hold the same in upright position. Means interposed between the oppositely located sides of the window openings and the inner ends of the braces, retain the last named elements in place. A carrier to which is pivoted a tipping bucket is slidl ably guided along the mast on which arealso mounted sheaves for the cable that leads to the hoist and controls the travel of the carrier. A linkage ljoin'tedly connecting the latter with the buc (et locks the same from tipping. Trips sustained from the braces are capable of vbeing set to release the linkage and thereby cause vdumping of the bucket at a. predetermined level. A chute supported upon the brace retaining means delivers the contents dumped thereon from the bucket thru the window opening selected therefor,

' The advantages of the invention as here outlined are best realized when all of its features and'instrumentalities are cplmbined\m' the one and same structure, but, useful de vices may be produced embodying less `than the whole.

.It will be obvious those skillad, in the art to which the inventionV appertalns, upon .becoming conversant with the details there.

' of, that-'thel same may be incorporated in l views for a detailedv description of 'this imseveral different constructions.` The acom'- panying drawings, therefore, are submitted merely as showing the preferred'exemplification of the invention.

Referring now to the before mentlone proved hoisting apparatus, the same comprises a mast or Vupright 1-1. The latter may be com osed of one or more pieces 1 1*,'11b made o stout timbers preferably of rectangular section and joined end to end. This mast is intended to reach a height somewhat above the level of the topwindow of a six story building which is about the highest structure contemplated to be served by an apparatus of the nature shown on the annexed.

drawings. To both of the narrower, front and rearsides of mast 11, are fastened as for instance by lag-screws 12, lengths of rails 13, 14, which as shown, maybe of angular cross-section, having the legs on one .side thereof turned outwardly and disposed flush with the wide, inner and according to Fig.

. VI, the right hand side of the upright 11.

Upon inspection of Fig. III, it will be observed that-at the places division of the mast sections occur, the angle iron-.rails 13, 14, on one of the sections 11, overlap or extend beyond the joint or where the other piece 11" abuts the one first named. In Vsaid Fig., III and also at the lower ortion of Fig. I, bolts 15, 15b are illustratedp as employed to clamp the rails and the mastl sections together. At

the meeting or abutting ends of said sections,

the first mentioned bolt 15a which is sustained b the rails 13, 14, a short distance belowthe ower extremity of theupper section 11, is adapted'to enter a groove 15?A formed in the upper end of the adjacent lower section .11". Thisis of material import because the yshank or body portion of said bolt 15, acts as a leader or feeler in finding its way into the crosswise disposed groove 15, when the section'or-mast-piece 11`IL is stepped into placeon top of theother'section 11'?, during the erection of the upri ht 11. -It is comparatively easy after the olt 15'* has entered the groove 15to pushthe companion bolt 15" thru the combined rails 14, 15, and the lower section 1.1",subsequently to which both bolts are tightened up to firmly connect and align the arts 11` and 11b.. It winbe un.V

derstood t at as many joints and `sections of the mast areused, as are needed to build it vup to the' required height. *.By. virtue of the sectional 'features of the mast, taken in conjunction with th'e. ease with which coupling together of is joints can be eifected, considerable saving lof time is afforded during erection, dismantling, as well as handling thereof incidental to its transportation.

Figs. IV and" VII indicate that the foot portion of .the mast 11 is rovided at opposite sides and at right ang es to therails13,

14, with clipsl7, 17", consistin of short piecesiof angle iron. Spikes ,orda (not shown) are driven lthru holes in these clips into an underlying heavy piece of timg-screws ber, platform A, or'the like, laid upon or set into the ground B, so as `to constitute a basal support for the said mast.

Surlnounting the upper extremity of mast 11, is a rope-sheave 19 which is revolvably supported on a pin 20 carried across the top portions of a frame,composed of similar but 'reversely disposed members 21, 21". The` lower extremities of thesemembers which terminate above the upper ends of rails 13, 14, clasp around the same sides of the mast, as the rails, being held thereto, as Vfor instance by thru Vbolts 22 (see Figs.A I and II).

Upon inspectionof the various views on thev accompanying drawings, it vwill be perceived that the mast therein represented, is fur# mshed with a series of spaced apart apertures 24, aligned in a vertical row centrally thru the vmasts thinner part. Or, stated 'in other words, the apertures referred to, are

' disposed at right angles to the plane in which the s1dew1se projecting2 free legs ofthe angu`- lar rails are situated. One 'of the purposes of apertures 24 is to receive bolts 25 by means of which a bracket 26 is affixed to thewider, rear or outer face of the mast 11. A double jawed arm 27 is pivotally connected by its the reference letters C1, C2, 03,0* and C5 so as to be easily traceable. The swivelable arrangement of the vsheave carrying arm,-en ables the hoist (rope-Winding drum and prime-mover, not shown) to be placed in any suitable position relatively to the mast,and

the cable led to sheave 29 from a'point where most convenient.

In the various views, the reference letter D denotes the outside face of a building wall, and E window openings therein at different levelsv or stories. From one side of these openings,`shown on the drawings as being the one on` the left, braces 30 reach out to moet the mast 11, for which a relatively heavy plank or piece of lumber may be employed. By wa of suitable openings 31, bored transverse y across the outer ends of these braces, one for each brace or outrigger as the same may also be termed, are passed bolts 32, as well as thru those of the apertures 24 inl the mast which happen to be in nearest alignment therewith. lIt is a comparatively easy matter, in order to bring the aforementioned openings and apertures into register, to block or shim up the inner or window engaging ends of the braces. To the last named ,ends of said braces, are attached cleats 33, 34, and to the outer faces of the same, clips 35, 36, which are coextensive therewith, respectively. The clips-just above referred to, may conveniently consist of short lengths of angle iron having one set of their legs turned outwardly so as to take around the inner and outer faces of the wall adjacent a window opening, thus locating the braces with respect to the building wall, and consequently also maintaining the mast in alignment therewith. It canclearly be seen from Figs. IV and VIII, that the cleats spoken of, are somewhat longer thanl the depth'of the braces, being held thereto by means of bolts 37a, 37", passing thru the clips 33, 34 as well, to secure them to the said cleats.

The means for retaining the mast holding braces in their assigned positions within the Window openings, comprise preferably, pairs of struts 39. 40, of substantially equal lengths. Said struts are disposed in diagonal offset relation with respect to the braces 30 and the opposed inner sides of the openings E. As will be observed from Figs. IV, VI and VIII, each of the struts 39 is interposed between an outer cle-at 33 on top of one'of the braces, and the usual exterior offset E1 formed in walls on the outside, adjacent to a window opening. The other strut 40 extends intermediate the inner cleat 34.-, underneath the same brace, and an interior offset E2 ordinarily occurring in walls on the inside, in proximity to the window opening. Both'struts are forced, as by driving or hammering them into their respective places, so as to preclude said struts from becoming loose and` relieve the crowding or bindingl action exerted against the braces wherewith they coact. vWhen itis desired to remove the braces 30, incidental to taking down the mast sections 11a, 11b, all' that is necessary, isto knock the struts 39, 40from the bolts 32 have been disconnected therefrom.

At 42 is indicated a plate or a series of boards nailed or otherwise affixed to the vertical and horizontally offset upper and inner corners of the struts 39, 40, so as to obtain a downward inclination from the outside to the interior of the building. The sloping plane thus afforded serves as a chute for material dumped thereon, as will `be more fully hereinafter referred to.

Upon the inner, -or the side of the mast or upright that faces a vertical plane passing centrally thru the window openings, is slidably mounted a carrier of substantially L-shape formation. In the preferred construction shown, this carrier consists of a one-piece channel-iron, including a vertical portion 50, disposed as represented in Figs. IV and VI. in parallelism with the righthand side of the mast l1, and a horizontal outwardly extendingleg 50h. The flanges of said channel are turned towards the mast so as to leave a clearance space therebetween for the heads or nuts of the bolts 32, when carrier 50, passes over them. A pair of arms 51a, 51h, spaced apart so as to leave a gap '51, intermediately thereof, are secured by rivets or the like, in overhanging relation and in close adjacency to the upper innerextremity of the carriers vertical web .portion 50a. To a pin or bolt 52 bridging gap 51' is anchored in any suitable Way, the terminal C of the hoisting cable.

From the front face of the channels web portion, project first sidewise, thence rearwardly, and finally inwardly towards the mast, keepers 53'whieh are located at fixed distances below the cable-anchorage arms and above the carrier leg 50', respectively. The inwardly bent portions of these keepers, designated 53, are arranged to overlie the outwardly turned legs of the angleiron rails 13, 14, and lodged between the opposed faces of said rail legs and said portions 53a, are

gibs 55 attached to the latter, which gibs may be exchanged for new ones when worn out. The last named portions of the keepers prevent disassociation of the carrier 50 relatively to the mast rail guides 13, 14. lVoodelr blocks 56a, 56, saturated with oil, are inserted into the interstices between the angular guides 13-14, the channelv flanges of the carrier vertical member 50, and the outer sides of the keepers 53, being by preference secured to the latter. These blocks not only function as wipers and lubricators, but prevent also the flanges of the portion 50a from rubbing on the adjacent face of the mast.

It w1ll be noticed with particular reference to Fig. I, that bracket members 57, 58, coact respectively with the top and bottom faces spout.

of the web portion pertaining to the carriers leg 50h, being removably held lthereto thru,

Upon said rod is hinged the lower lobe-A Iiike terminals of straps 6l, 62, fastened to the fiat, longitudinal sides cfa scoop-shaped bucket 63. For the purpose of imparting `rigidity to theaforesaid straps, they are, tied to the bottom of bucket 63, by an inverted bail-like brace 64. The inner, or .the side of this bucket which faces the window openings, is formed on the order of a straight nosed To the opposite, transverse and curved side of the bucket, turned outwardly or away from the wall, is secured at a level about two-thirds down from the top of said bucket, a bar 66, having screw-threaded shanks 66, 66", at the extremities thereof. At such times as the bucket is used in conjunction with a mast disposed at the left hand side of a roW of vertically aligned kwindow openings, as shown, shank 66, at the corresponding side of the said bucket, has hingedly connected thereto, one terminal of a link 67. kThe latter has a similar connection with the adjacent end of a lever 68 pivoted at 69 intermediate its extremities, to the inner branch of a double armed support 70, ailixed to the carriers member 50, directly above the lower one of the keepers 53. The middle portion of link 67 as well as the inner extremity'of lever 68, i. e. the part thereof which reaches inwardly towards the fwall D, are both oii'set laterally in order to bring these elements in close adjacency, respectively to the upright member 50a of the carrier, and to the vertical plane wherein the mast-braces 30 are situated (Fig. VI) Swivelly attached to the mast facing sides yof the last named elements, in proximity to the window engaging ends thereof, are trips 71. Each one of these trips can be swung independently ofthe others so as to bring a. toe 71'3L wherewith the lowermost extremity thereof is provided, into or out of the path of the free terminal of the lever 68, when-the same travels past one or the other of the trips, incidental to hoisting o'r lowering of the carrier 50 and the thereon vmounted bucket 63.

As seen most advantageously from Figs. IV and VI, there is hinged to the free end of said lever 68, a latch-like extension 68,

` which is so constructed and arranged as to remain rigid with the said lever when it encounters an obstructlon, namely, toe 71, during upward travel of the bucket carrier.

But which, at such times as the latter is lowered, will permit the latch in striking the toe mentioned, to yield or fold upwardly,

enabling the lever 68 to idly or unaiectedly pass by. The overweighted condition of latch 68' causes the same to immediately resume its normal alignment with' the said lever, as soon as the former has passed the obstruction referred to. Obviously, if the toe 71 is placed in non-tri ping position, 1. e., swung out 'of reach o the latch 68", the last mentioned instrumentality willremain inoperative while the carrier is moved either up or down.

At such times,'as one of the elements 71 is placed in tripping position, as indicated in Fi V and also at the middle portion of Fig. V II, the bucket 63 is timed to tip over and discharge its contents u n, the chute 42.- The operator in charge o the hoisting motor or engine, naturally stops and holds the latter as soon as the bucket arrives at the position depicted by Fig. V, to permit the matev rial contained in the bucket to flow out, as well as to enable a workman stationed at the window opening, thru which-the deliver takes place, to scrape out, if necessary, suc

of the plaster or concrete that may adhere to the buckets interior. Upon being lowered, the inner or spout pointed end of the bucket, in striking against the top strut 39, swings the bucket back into horizontal position. And, after the bucket rests on or near the surface of the ground (Fig. IV), the person who does the charging, sees to it`that the bucket is locked in the level position thereof, represented bythe re last referred to. It will also be notice from this figure, that a bolt 69 which affords a toggle joint and couples the adjoining extremities of link 67-and lever 68, stands below the other pivotal connections 66 and 69, thus locking the joint mentioned until the same is positively position. Even if the location of mast 11 is reversed, from the one illustrated, that is, disposed on the right hand side of the window openings, with the lever 68 fulcrumed at the otherl or opposite arm 7 0* of the support 70, the said lever 68 will in its depressed position contact with clip' 73.

As represented in the upper right hand portion of Fig. IV, the trip lever 71, instead of being fulcrumed direct to the wooden brace 30, can advantageously be pivotally mounted on a plate 75 which is secured to the window facing or deeper side of the said mast brace. The portion of the trip lever that is oscillatable above its'pivotal centre,

by preference, is .guided by a strap 76 overbe arranged to bear frictionally on the side of the trip-lever so as to retain the latter in adjusted position.

From the foregoing it will be understood that a light, easily put-up hoisting apparatus is produced. With such anv a paratus the different fioors of medium hig buildings can conveniently be served from the outside to deliver thru the various, aligned window or otheropenings therein, small quantities -at one time, of plaster, sand, cement and the like, required for the interior finishing of the structure during completlon of its erection. By reason of the fact/that the hoisting bucket has two of vits adjacent sides exposed or unobstructed, the readyS. mixed or dry plaster, or cement or mortar can be quickly filled into the bucket by the attending workmen either by hand shovelling or direct from a mixing machine. The raising, dumping and returning of the bucket to charging position, can be accomplished in but a few seconds of time, by the one man in control of the hoisting engine,.thus effecting a great'saving of time and reducing the 'cost of handling material to a minimum.

The apparatus hereinbefore described, is designed for rapid dismantling and transportation from one building jobk to another and is therefore made in sections, comparatively light in weight and of small s izefor convenience of carrying by a couple of men. The component parts of the mast and braces are proportioned for ample strength. and

-' durability for the maximum loads contemplated to be imposed thereon. The mere swinging of a tripping lever from inclined to straight position will cause the bucket to i deposit its charge at a predetermined Hoor level. l

While a certain preferred embodiment of this device has been shown and described, it will be understoodthat changes in the form, arrangements, proportions, sizes and details thereof may be made, without departing from the scope of the invention as defined by the appended claims.
